Z3 is a theorem prover and satisfiability modulo theories (SMT) solver. It provides a C/C++ API, as well as Python bindings.

PETSc, pronounced PET-see (the S is silent), is a suite of data structures and routines for the scalable (parallel) solution of scientific applications modeled by partial differential equations.

On modern CPUs and GPUs, integer division is several times slower than multiplication. FXdiv implements an algorithm to replace an integer division with a multiplication and two shifts. This algorithm improves performance when an application performs repeated divisions by the same divisor.

This package provides a Django front end for Mathics3.

UMFPACK is a set of routines for solving unsymmetric sparse linear systems using the Unsymmetric MultiFrontal method and direct sparse LU factorization.

CAMD is a set of routines for ordering a sparse matrix prior to Cholesky factorization (or for LU factorization with diagonal pivoting). It is a variant of AMD which has the the option to apply constraints to the ordering.

OpenBLAS is a Basic Linear Algebra Subprograms (BLAS) library forked from the GotoBLAS2-1.13 BSD version.

DUNE, the Distributed and Unified Numerics Environment is a modular toolbox for solving partial differential equations (PDEs) with grid-based methods.

This is the iterative solver template library which provides generic sparse matrix/vector classes and a variety of solvers based on these classes. A special feature is the use of templates to exploit the recursive block structure of finite element matrices at compile time. Available solvers include Krylov methods, (block-) incomplete decompositions and aggregation-based algebraic multigrid.

SLEEF (SIMD Library for Evaluating Elementary Functions) is a library that implements vectorized versions of all C99 real floating point math functions. It can utilize SIMD instructions that are available on modern processors.

This header-only C++ library implements conversion to and from half-precision floating point formats.

This package provides the Blis BLAS-like linear algebra library, as a self-contained C-extension for Python.

AMD is a set of routines for ordering a sparse matrix prior to Cholesky factorization (or for LU factorization with diagonal pivoting).

SUNDIALS is a family of software packages implemented with the goal of providing robust time integrators and nonlinear solvers that can easily be incorporated into existing simulation codes.

This package provides the non-graphical version of the Scilab software for engineers and scientists. Scilab is used for signal processing, statistical analysis, image enhancement, fluid dynamics simulations, numerical optimization, and modeling, simulation of explicit and implicit dynamical systems and symbolic manipulations.

This is a filter for HDF5 that uses the Blosc compressor; by installing this filter, you can read and write HDF5 files with Blosc-compressed datasets.

The Interior Point Optimizer (IPOPT) is a software package for large-scale nonlinear optimization. It provides C++, C, and Fortran interfaces.

Kiwi is an efficient C++ implementation of the Cassowary constraint solving algorithm. Kiwi has been designed from the ground up to be lightweight and fast. Kiwi ranges from 10x to 500x faster than the original Cassowary solver with typical use cases gaining a 40x improvement. Memory savings are consistently > 5x.

NetCDF is an interface for scientific data access and a software library that provides an implementation of the interface. The netCDF library defines a machine-independent format for representing scientific data. Together, the interface, library, and format support the creation, access, and sharing of scientific data.

This package provides a prototype Python implementation for SAT-based problems.

MiniZinc is a high-level modeling language for constraint satisfaction and optimization problems. Models are compiled to FlatZinc, a language understood by many solvers.

feedgnuplot is a tool to plot realtime and stored data from the command line, using gnuplot. It can read data from a pipe or file, make a variety of transformations, and render the result in the terminal or with an external viewer.

Frama-C is an extensible and collaborative platform dedicated to source-code analysis of C software. The Frama-C analyzers assist you in various source-code-related activities, from the navigation through unfamiliar projects up to the certification of critical software.

This package contains software that will allow you to use existing neural network potential parameterizations to predict energies and forces (with standalone tools but also in conjunction with the MD software LAMMPS). In addition it is possible to train new neural network potentials with the provided training tools.

mCRL2 (micro Common Representation Language 2) is a formal specification language for describing concurrent discrete event systems. Its toolset supports analysis and automatic verification, linearisation, simulation, state-space exploration and generation, and tools to optimise and analyse specifications. Also, state spaces can be manipulated, visualised and analysed.
